Difference between LA County and LA City

Hey guys, just interested in the two departments and wanted to know, well, what exactly is the difference between LA County and LA City fire departments? Is there a difference? If so, please elaborate.

In my 33 years with the County I have seen about 20 guys come to the County from the City. And they were very happy about doing it. None that I heard of that went to the City
Pay about the same, I understand the County retirement is better.

"I have a dream. It's not a big dream, it's just a little dream. My dream — and I hope you don't find this too crazy — is that I would like the people of this community to feel that if, God forbid, there were a fire, calling the fire department would actually be a wise thing to do. You can't have people, if their houses are burning down, saying, 'Whatever you do, don't call the fire department!' That would be bad."
